摘要：

针对新能源汽车无序充电给电力系统带来的负荷压力等问题，提出了一种新能源汽车与风光发电协同优化调度策略。首先，建立了新能源汽车动力电池模型，并提出了基于蒙特卡洛模拟法的充电负荷计算方法。其次，基于风光发电原理建立了风力发电和光伏发电的数学模型。最后，以最小化电网等效负荷标准差为目标，利用有效集算法求解了二次规划问题，得到了新能源汽车的最优充放电调度策略。仿真结果表明：本文所提出的协同优化调度策略能够有效降低大规模新能源汽车无序充电加剧的电网负荷峰谷差。

Abstract:

A coordinated optimal dispatch strategy of wind and photovoltaic generation and new energy vehicles was proposed for the problem， which is caused by large-scale new energy vehicles disorderly charging in power grid. Firstly， the model of new energy vehicles power battery was built， and a calculation method of charging load based on Monte Carlo method was proposed. Secondly， based on the principle of wind and photovoltaic power generation， the mathematical models of wind power generation and photovoltaic power generation were established. Finally， The objective function of the dispatch strategy is to minimize the standard deviation of the comprehensive load of the power grid， and the active set algorithm was utilized to solve the quadratic programming problem to obtain the coordinated optimal dispatch strategy. The simulation results show that the strategy can effectively avoid the aggravating difference between peak and valley load， which is caused by large-scale new energy vehicles disorderly charging in power grid.
